Benefits Of zkSync Smart Contract Audit

We Solve
Puzzles

While others run automated tools to catch the usual suspects, we dive deeper. Every project is unique, and so are its hidden bugs. Our game-theoretic audits tackle the tough ones, uncovering vulnerabilities that others miss.

No Bias, Just Blind Audits

Our audit team works in silos, tackling your code from different angles without influencing each other. At the end, we bring all the pieces together for unbiased results. No bias, no stone left unturned, just top-notch security findings.


Polymath Problem Solvers

We don’t just focus on code. We bring together economics, philosophy, finance, and computer science to solve your toughest problems. It’s like having a whole think tank dedicated to your project’s security.


We’re in this together

We dedicate as much time to understanding your needs as we do to auditing your code. From the start, we add code instrumentation for better debuggability and apply tailored techniques like fuzzing and formal verification to meet your specific requirements
Our Methodology
Pre-Audit
The process is initiated with code freeze and gathering documentation i.e., codebase, whitepaper, etc. to give us a clear picture of your project.
Automated & dynamic Testing
We use industry-leading security tools to analyze your code for vulnerabilities across different blockchain languages.
Line-By-Line Code Review
Our security experts meticulously examine every line of your code, identifying security weaknesses and opportunities for gas optimization.
Initial Report
We provide a draft report with findings and suggestions for fixing the issues. We work with you to implement the fixes and ensure no new problems arise.
Publish Final Audit Report
Once the fixes are reviewed, we deliver the final public report, building transparency and trust with investors and users.

Know your Bugs

Logic Errors

Integer Overflow

Reentrancy Attacks

Denial-of-Service (DoS) Attacks

Uninitialized Variables

Mistakes in the code’s logic can lead to unintended consequences, potentially allowing attackers to manipulate the contract or steal funds.
Errors in handling mathematical operations can lead to unexpected results, potentially allowing attackers to manipulate token balances or transaction fees.
A vulnerability where a function can be called multiple times before the first call finishes, potentially allowing attackers to exploit this gap to steal funds.
Malicious actors could spam the network with transactions, overloading validators and preventing legitimate transactions from being processed.
Variables that haven’t been assigned a value can lead to unpredictable behavior and potential vulnerabilities if exploited by attackers.

Even the most innovative zkSync projects can harbor vulnerabilities. A BlockApex audit acts as a security shield, identifying potential exploits before attackers can strike.
Transparency is key. BlockApex prioritizes a collaborative approach. We work closely with your team, providing clear and actionable insights to continuously strengthen your zkSync dApp's security posture. The specific steps may vary depending on your project
Early detection is key! BlockApex offers smart contract audits at various stages of development. An early audit can identify and address potential vulnerabilities before they become entrenched in your codebase, saving you time and resources in the long run.
The zkSync protocol undergoes upgrades to enhance functionality and security. While a re-audit isn't mandatory after every upgrade, it's a wise precaution.
